I have a JavaScript function which is embeded in an XSL file, I am using this to try and bring back a list of strings based on a number of rows in an XML file.

The problem I have is that I do not have the url of the XML file as this is created on the fly so I cannot load this in to look at the specific nodes of the file.

I am therefore trying to get some info from the XML file using an XSL tranformation in my javascript code. This works great, apart from one part of the code which I cannot get to use the variable "i". This is the part [@index=1] in the code below.

Instead of [@index=1] I want it to be [@index=i+1] and use the variable i to determine what row index to use in the code. When I try this however it just brings out a null value.

I have tried things such as trying to split the text

"<xsl:value-of select="Data/DataRow[@index=1]/ID" />"

into

"<xsl:value-of select="Data/DataRow[@index="
+(i+1)+
"]/ID" />"

but this brings up an error saying "The XSL could not be parsed. The error is Name cannot begin with the '+' character, hexadecimal value 0x2B. Line 16, position 99."

Any help would be greatly appreacted as I am pulling my hair out trying to get this to work.

Many thanks,

Laurence

for (var i = 0; i &lt; inputList.length; i++)
Makes me cringe. I'd use
for (var i = 0; i<inputList.length; i++)
and be a lot happier.

Try:
+'<xsl:value-of select="Data/DataRow[@index="+(i+1)+"]/ID"/>'

Enclosing the double quotes inside of singles.

I'm not responding here to the original post, but am commenting on the previous one.

Difficult to distinguish the quotes from the apostrophes (a.k.a. single-quotes) on my display, but it appears that they are not paired properly:

'<xsl:value-of select="Data/DataRow[@index="+(i+1)+"]/ID"/>'

might be intended as

'<xsl:value-of select=\'Data/DataRow[@index="' + (i+1) + '"]/ID\'/>'

wherein the quotes that are adjacent to plus signs, like the initial and final quotes, are all apostrophes, the index attribute's value is wrapped in real double-line quotes, and the value of the select attribute is wrapped in escaped apostrophes (single-quotes). That way, the final will look something like: <xsl:value-of select='Data/DataRow[@index="10"]/ID' />.

My XSLT is somewhat rusty, but I think there's a problem with the /ID after the @index - it should not be there. You might want to make sure that your code correctly builds your querystring. Why not set up an alert and see what the concatenated querystring looks like and make sure it is correctly formatted?

In case you have not yet discovered it, zvon.org is one of the noted sites for xslt documentation and examples. Perhaps you will find what you are looking for there.
